In the Netherlands, we’re holding levee (dike) experiments at the IJkdijk
location. Two levees have been build, stuffed
full with various sensors.

The goal? To get those levees to break and to validate which sensors provide
useful monitoring data. There are two types of failure which they’re testing:

Piping. A sand layer
is placed under the levee where water can seep through, undermining the
levee.

Macro stability. Tanks of water are placed on top of the levee, pushing
water into the inner part of the levee. After a while, the pressure is too
big and the levee will burst/collapse/fail.

All those monitors are connected to a central database. We (Nelen &
Schuurmans) participated together with
Fugro. Fugro loaded the data into their Geodin database, we showed the data in a website using our
Lizard (build with Django) framework.

What we used a lot: the Flot javascript graph
library for beautiful graphs.

The website is only accessible on the experiment location itself, so I made
myself a short movie so you can get an idea anyway:
